Disable hostname lookup on chain exists check#1974
Merged
Conversation
Without `-n`, iptables will attempt to lookup hostnames for IP addresses, which can slow down the call dramatically. Since we don't need this, and generally don't even care about the output, use the `-n` flag to disable this. Signed-off-by: Brian Goff <cpuguy83@gmail.com>

@mavenugo can you add some label so that we don't miss the backport? |
